Oh, I forgot about this one! (Take-away related)
I had been telling my obstetrical nursing students the day before about how some cultures ate placenta and not to be surprised if the parents asked to take theirs home.

The next day, I came in and someone had brought in Chicken Something from the Orient Gardens carry-out covered in that violently Chinese-red slop. I hatched a brilliant plan: I put it in a styrofoam coffee cup and took it into the student's room.

"Hey, you guys, remember when I said some people liked to eat their placentas? Well, the lady in room 39 had her mom cook hers up and brought it in. I asked her if I could have a little to share with my students." They see the bright crimson, gooey chunks on the end of my fork and turn white.

"Does anyone want to try it? I'm going to see what it tastes like.." and I raise the drippy thing to my lips. Before I can laugh and say, "Just kidding!", Kevin turns and hurls into the wastebasket and Belinda's eyes roll back in her head and she has to sit down fast.
